• *1: If two or more wheel speed sensor are defective, ABS warning lamp, EBD warning lamp and
ESP
® warning lamp are lit and all the control functions are deactivated. If one wheel speed sensor is
defective, ABS warning lamp and ESP
® warning lamp are lit and ABS and TCS / stability control are
deactivated.

® warning lamp are lit and ABS and TCS / stability
control are deactivated. For 2WD vehicle, ESP
® warning lamp is lit and TCS / stability control is
deactivated.
• *3: ESP
® OFF mode is cancelled and all control functions are activated.
• *4: EBD control function is activated only if power supply circuit is low voltage malfunction.

Scan Tool Data
S5JB0E4604024
The parameter data below are values measured with the scan tool when the normally operating vehicle is under the
following conditions. When taking measurements for comparison by using the scan tool, be sure to check that the
vehicle is under the following conditions.
• Apply parking brake and block wheels.
• Ignition switch ON.
• Turn OFF air conditioning (if equipped).
• Set the wheel in straight-ahead position and hands off steering wheel.
• Turn OFF all electric loads (except ignition).
• Check that there is no DTC.
Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ESP
® control module. Certain
ESP
® control module functions will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Driver (V): This parameter indicates the
operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed
and LR Wheel Speed (km/h, MPH): Wheel speed
is ESP
® control module internal parameter. It is
computed by reference pulses from the wheel speed
sensor.
Brake Switch (ON, OFF): This switch signal informs
the ESP
® control module whether the brake is active
or not.
G Sensor (G): Vehicle acceleration is measured by yaw
rate / G sensor assembly and output to ESP
®
control module by pulse signal for 4WD vehicle.
Master Cyl Press (MPa): Brake fluid pressure from
brake master cylinder.
G Sensor (lateral) (G): Lateral acceleration is
measured by yaw rate / G sensor assembly and
output to ESP
® control module by pulse signal.
Yaw rate sensor (Deg/s): Yaw rate sensor is measured
by yaw rate / G sensor assembly and output to
ESP
® control module by pulse signal.
Steering angle Sen (
°): Steering wheel rotation angle
is measured by steering angle sensor and output to
ESP
® control module by pulse signal.
Stability control (ACTIVE, INACTIVE): This indicates
stability control in activation / deactivation.
TCS control (brake) (ACTIVE, INACTIVE): This
indicates brake function of TCS in activation /
deactivation.
TCS control (engine) (ACTIVE, INACTIVE): This
indicates torque control of TCS in activation /
deactivation.
ESP
® off state (cont) (ESP® ON, ESP® OFF): State
of ESP
® OFF switch.
Steering angle Sen (Neutral, NONnewtral): This
indicates steering wheel angle measured by steering
angle sensor is in straight-ahead or not.

ESP
® Warning Lamp Does Not Come ON at Ignition Switch ON
S5JB0E4604008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ESP
® warning lamp is controlled by ESP® control module through lamp driver module in
combination meter.
If ESP
® system is in good condition, ESP® control module turns ESP® warning lamp ON at the ignition switch ON,
keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ESP
® warning lamp is
turned ON continuously by ESP
® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP
® control module is disconnected.

1
1) Turn ignition switch to ON position.
Do other warning lamps come ON?
Go to Step 2.
Go to Step 3.
2
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch to OFF position and check DTC.
Is there DTC U1073?
Go to “DTC U1073:
Control Module
Communication Bus
Off” for troubleshooting.
Substitute a known-
good combination meter
and recheck. If ESP
®
warning lamp remains
OFF, substitute a
known-good ESP
®
hydraulic unit / control
module assembly and
recheck.

Is Circuit fuse for combination meter in good condition?
Go to Step 4.
Replace fuse and check
for short circuit to
ground.

1) Check CAN communication circuit between combination
meter and ESP
®, control module referring to “DTC
U1073: Control Module Communication Bus Off”
Is CAN communication circuit in good condition?
Go to Step 5.
Repair or replace.
